INGOLSTADT : September 24, 2014 - Purity in its most beautiful form: Audi is presenting the new TT
Roadster* and the TTS Roadster* at the Paris Motor Show. The compact
two-seater sets new standards in design, drive, and suspension. A
particular highlight in the third TT generation is the Audi virtual
cockpit. For the first time, the digital instrument cluster provides all
information within the driver’s field of vision – a concept that is
causing a sensation. This has already led to the Audi TT’s new display
and control system receiving the Car Connectivity Award and the honor of
Interior Innovation of the Year at the Automotive Interiors Expo
Awards.

“The concept of designing a compact roadster following clear
geometrical rules formed the original idea for the Audi TT in autumn
1994,” says Prof. Dr. Ulrich Hackenberg, Board Member for Technical
Development at AUDI AG: “From the first generation on, it has been a
sports car for the senses – a driving machine with an authentic design.
With the new TT Roadster, we have developed this concept in a consistent
manner and further improved the technical experience in the car with
innovations such as the Audi virtual cockpit.”

A design that is
full of character is fused with timeless aesthetics – the
third-generation TT Roadster and the TTS Roadster mark the continuation
of a great tradition. The Audi designers have reinterpreted the styling
of this classic vehicle and complemented it with innovative components.

New from the ground up: the control system

The
control system in the new Audi TT Roadster and TTS Roadster is fully
focused on the driver. There are two variants of the new multifunction
steering wheel available. Thanks to the fundamental redevelopment of the
control logic, the reworked MMI terminal features six hard buttons. The
natural language control also makes it easier to operate the system
when driving.

In combination with the MMI navigation plus, the
MMI touch – the touchpad on top of the rotary push-button – is also on
board. The driver can use this to scroll through lists, zoom in on maps,
and enter characters. The menu structure is inspired by the layout of a
smartphone and includes free text search. All key functions can be
reached with just a few clicks, and the buttons on the side provide
access to intelligently linked functions and options.

Another top
innovation in the new TT generation is the Audi virtual cockpit. With
its versatile, detailed depictions, the digital instrument cluster
replaces the analog instruments and the MMI monitor. It is possible to
toggle between two levels of the 12.3‑inch display. The classic view is
dominated by the tachograph and the rev counter, whereas “infotainment”
mode focuses on themes such as the navigation map. The TTS Roadster
features a third, particularly sporty view that focuses on the rev
counter as an important racing instrument.

A further highlight of
the new model generation is the voice control, which has been made
significantly easier. The system now understands phrasings from everyday
language, meaning that hundreds of command variations are possible for
each function. In the telephone menu, for example, calling a contact is
as easy as saying “I want to talk to Peter” or “Connect me to Peter.”
The natural language control is also integrated into the navigation,
radio, and media menu items, providing customers with consistent
language control.

The fun of open top driving: the conceptThe
new TT Roadster combines the dynamic ride of a sports car with the
driving experience of an open‑top two‑seater. The basis for this
consists of struts in the underbody and body that considerably improve
both the torsional rigidity and the ride comfort.

The new
TT Roadster is sporty, compact and low-slung stance on the road. At
4,177 millimeters (13.7 ft), the two‑seater is 21 millimeters (0.8 in)
shorter than its predecessor. The wheelbase, on the other hand, has
grown by 37 millimeters (1.5 in) to 2,505 millimeters (8.2 ft). The
overhangs are correspondingly short. Featuring a width of
1,832 millimeters (6.0 ft), the new TT Roadster is 10 millimeters
(0.4 in) narrower than its predecessor and has a height of
1,355 millimeters (4.4 ft) (3 millimeters [0.1 in] less). Its drag
coefficient is only 0.30 with the top closed – number one in the compact
sports car segment. This is down to Audi having combined the
distinctive design with excellent aerodynamics.

The front of the
open‑top sports car conveys power and energy through its accentuated
horizontal lines. Similar to the Audi R8*, the Singleframe grille is
wide and flat – the four rings are positioned on the hood in the style
of a high-performance sports car. On the standard version, the air
inlets are connected to one another and divided by two vertical slats.

Two
vertical lighting elements are also positioned in the headlights and
emit the daytime running lights. Audi optionally supplies the headlights
in LED technology. The headlights will also be available in the new
Matrix LED technology shortly after the market launch – in this case,
the high beam is produced by small, individually controlled light
emitting diodes. In the Matrix LED headlights, the indicator featuring a
dynamized display – another brand innovation – runs in the direction
selected by the driver.

The flat and taut top of the new
TT Roadster and the TTS Roadster also provides a clear contrast with the
body and is defined by the short side window design that is typical of
the TT Roadster. When viewed from the side, many of the details invoke
the first generation of the design classic. The shoulders have a
muscular look and the sill contour forms a strong light-refracting edge.
The broad wheel arches form their own geometric entities: The front
wheel arch breaks through the hood gap that continues as the tornado
line all the way to the rear end. The driver no longer needs to unscrew
the cap underneath the classic round tank flap on the right side. Direct
refueling is performed in true racing style.

At the rear,
horizontal lines again underscore the width of the open‑top sports car.
The bars in the standard LED rear lights, which adopt the motif of the
headlights, are permanently illuminated. The third brake light – a flat
strip on the edge of the luggage compartment lid – connects the light
silhouette at the rear. A diffuser incorporates the tailpipes of the
exhaust system. At speeds of 120 km/h (74.6 mph) and above, a spoiler is
electrically extended from the luggage compartment lid to provide
additional downforce on the rear axle.

2015 AUDI TTS Roadster

Light and quiet: the convertible topAs with all
Audi Cabriolet models, the new TT Roadster and the TTS Roadster also
feature an electrically actuated fabric top. This is available as
standard in black, titanium gray and jive, and fits perfectly into the
design line. With parts made from magnesium, aluminum, steel and
plastic, the soft top weighs just 39 kilograms (86.0 lb) and is
3 kilograms (6.6 lb) lighter than its predecessor. This has a positive
impact on the gross vehicle weight and the center of gravity of the
open‑top two seater.
While opening, the top forms a Z shape as it
folds together into a flat package. When is stowed in the aluminum tray,
it does not encroach on the 280‑liter (9.9 cu ft) luggage compartment.
The electric drive with the two electric motors performs opening and
closing in 10 seconds, even when driving at speeds of up to around
50 km/h (31.1 mph). As a result of the elaborate clamping technology,
the closed top is completely taut even at high speeds – it features a
homogeneous look that conceals the cross bows.

The acoustic top is
already fitted as standard on the Audi TT Roadster and Audi
TTS Roadster and is noted for its extremely good thermal insulation and a
low noise level, especially in the frequency range of the airflow. The
thick fleece layer on the black inner headlining adds comfort. Depending
on frequency, the noise level in the interior has been reduced by up to
6 dB compared with the predecessor. The aerials for radio reception are
hidden from view by the convertible top. An electric mesh wind
deflector and the S sport seats including headroom heating are
optionally available.

Intelligent composite construction: the bodyThe
body of the TT Roadster and the TTS Roadster represents a new evolution
of the Audi Space Frame (ASF) based on the modular transverse matrix
(MQB). Ultra-high-strength components made from hot-shaped steel
reinforce the front section and the passenger compartment floor. The
passenger compartment and all outer skin and attachment parts are made
of the classic semi-finished aluminum products cast node, extruded
profile and sheet metal.

With the 2.0 TFSI and manual
transmission, the unladen weight of the TT Roadster (without driver) is
only 1,320 kilograms (2,910.1 lb). The Audi engineers have also further
improved the crash safety through the intelligent composite concept in
the TT Roadster.

Compared with the Coupé, the body of the Roadster
has been modified in important areas. The aluminum A‑pillars each
conceal a second steel pillar in their interior, which in turn houses a
solid steel tube. Internal steel ribbing ensures the aluminum sills have
high-strength properties. V‑shaped steel struts reinforce the zones
underneath the engine compartment and the luggage compartment, and
connect the axle carriers.

In the TT Roadster and the
TTS Roadster, a solid wall consisting of two box profiles separates the
interior from the luggage compartment, and replaces the bottom cross
member found on the Coupé. The upper area of this wall houses the steel
roll-over bars, whose elegantly rounded form marks another classic
design theme. Mounting plates seal the openings in the rear wall, which
features through-loading as standard.

Powerful and efficient: the enginesThe
new TT Roadster is being launched with two turbocharged four-cylinder
engines, a TDI and a TFSI. A powerful TFSI ensures efficient drive in
the TTS Roadster. With power outputs between 135 kW (184 hp) and 228 kW
(310 hp), they clearly surpass the respective predecessor engines in
terms of power, while significantly undercutting them with regard to
consumption.

Using the modular transverse matrix, all engines are
mounted in the same place – their installation location has great
advantages with regard to packaging. A start‑stop system is included as
standard. In combination with the optional driving dynamics system Audi
drive select (fitted as standard on the TTS Roadster), the adjustable
engine sound makes the sound even more sonorous.

Featuring 135 kW
(184 hp) and 380 Nm (280.3 lb‑ft) of torque, the 2.0 TDI ultra is
already a sporty engine. As with all engines in the new TT family, the
two‑liter diesel engine meets the Euro 6 standard. It averages just
4.3 liters of fuel per 100 kilometers (54.7 US mpg), which equates to
CO2 emissions of 114 grams of CO2 emissions per kilometer (183.5 g/mi) –
a new best figure in its segment.

The 2.0 TFSI produces 169 kW
(230 hp) and 370 Nm (272.9 lb‑ft) of torque in the TT Roadster; in the
TTS Roadster, these figures are as high as 228 kW (310 hp) and 380 Nm
(280.3 lb‑ft). The top model breaks into the high-performance range,
sprinting from 0 to 100 km/h (62.1 mph) in 4.9 seconds on its way to an
electronically governed top speed of 250 km/h (155.3 mph). The
switchable flaps in the exhaust system underscore the sporty sound.

The
2.0 TFSI channels its output to a manual six‑speed transmission; the
output can optionally be channeled to a six‑speed S tronic. The
dual-clutch transmission shifts rapidly through the gears without any
noticeable break in propulsive power and can be controlled by paddles on
the steering wheel if desired. In efficiency mode in the Audi drive
select system, the S tronic coasts when the driver takes their foot off
the gas.

New technology: quattro permanent all-wheel driveThe
quattro permanent all-wheel drive has been fully redeveloped; it is
optionally available in combination with the 2.0 TFSI engine in the
TT Roadster and is fitted as standard on the TTS Roadster. During
regular driving, its electrohydraulic multi-plate clutch optimally
distributes the drive torque between the front and rear axle depending
on driving conditions, road characteristics and driver type.

Driving
enjoyment and safety are combined at a new level by electronic clutch
management. More power is routed to the rear axle during sporty driving,
literally propelling the new TT Roadster and the TTS Roadster into
corners. Safe, controlled drifts are possible on low-friction surfaces.
The
third TT generation is the first in which the permanent all‑wheel drive
is integrated into the dynamic handling system Audi drive select. The
driver can use this to toggle the engine characteristics and the
operation of the steering support between the comfort, auto, dynamic,
efficiency and individual modes. Audi drive select also accesses a
series of optional technical modules including the adaptive damper
control Audi magnetic ride (fitted as standard on the TTS Roadster) and
the six-speed S tronic.

A synthetic hydrocarbon oil containing
microscopically small magnetic particles circulates within the damper
pistons. Each of the front dampers contains 154 milliliters (6.1 in),
the rear dampers 185 milliliters (7.3 in) apiece. When a voltage is
applied to a coil, a magnetic field is generated in which the alignment
of the particles changes so that they are perpendicular to the oil flow,
thereby inhibiting its flow through the shock absorber channels.

The
control unit continuously analyzes the driving properties and the
condition of the road. Depending on the setting in Audi drive select,
the ride of the new Audi TT Roadster and the TTS Roadster is either
relatively comfortable, balanced or decidedly taut. The dynamic mode
unveils its full dynamic potential. The targeted bracing of the
individual wheels during fast cornering ties the Roadster tightly to the
road. It largely suppresses roll and makes steering response even more
spontaneous. Audi magnetic ride reduces body pitch during braking.

Sporty and stable: the chassisThe McPherson
principle is used for the front suspension of the new Audi TT Roadster
and the TTS Roadster. Aluminum components reduce the weight of the
unsprung masses. The steering rack of the standard progressive steering
is designed so that the steering ratio becomes increasingly direct when
turning. The rear axle, which features four steel links per wheel, can
handle the longitudinal and transverse forces separately.

Together
with the progressive steering, the sophisticated suspension and the
taut tuning lead to high-precision dynamic handling. The body is lowered
by 10 millimeters (0.4 in) on the TTS Roadster, in conjunction with the
S line sports package and with Audi magnetic ride. The TT Roadster
2.0 TFSI and the TT Roadster 2.0 TDI roll on 17‑inch lightweight wheels,
each of which weighs only 8.7 kilograms (19.2 lb); the tire dimension
is 225/50. On the TTS Roadster, the format is 18 inch and the tire size
245/40; the available options range up to 20‑inch format. The newly
developed tires are noted for their improved performance together with
significant optimization of rolling resistance.

Brakes that can be
precisely metered and convey a taut pedal feel are located behind the
large wheels. The vented front discs have a diameter between 312 and
338 millimeters (12.3 – 13.3 in) depending on the engine version. The
TTS Roadster features newly developed, particularly lightweight aluminum
fixed-caliper brakes on the front axle. Another innovation, the
electromechanical parking brake, takes effect at the rear wheels
regardless of engine version.

The Electronic Stabilization Control
(ESC), which can be switched off either partly or completely, perfectly
complements the car’s sporty handling. Wheel-selective torque control
takes effect when cornering: Where necessary, it can distribute the
drive torque from the front wheel on the inside of the curve to the
front wheel on the outside of the curve (in the case of
front‑wheel drive). With quattro drive, this is also performed at the
rear wheel. The car turns very easily into the curve thanks to the
difference in propulsive forces, which is helpful for the driver. This
enables more precise and neutral driving around curves, with the
TT Roadster realizing a major boost in terms of dynamics and stability.
Sports mode facilitates particularly sporty driving, facilitating
steering and control when drifting.

New line: the interior designThe
two-seat interior of the new TT Roadster and the new TTS Roadster fits
around the driver like a custom-made suit. It has an intimate and
protective feel, particularly when the fabric top is closed, without
ever being restrictive. The curb clearance is high and the newly
developed sport seats with integrated head restraints are mounted low.
Together, they weigh five kilograms less than the seats in the
predecessor. The S sport seats are optionally available (standard in the
TTS Roadster) and feature particularly powerful, pneumatically
adjustable bolsters.

With its light, almost floating lines, the
interior continues the line of the exterior. The interior’s central
concept is focus on the driver. All controls are grouped around the
driver – a statement in favor of sporty, dynamic driving. The door trims
and the center tunnel console feature flowing forms that correspond
with one another.

When viewed from above, the sleek instrument
panel resembles the wing of an airplane; the round air vents – a further
traditional TT feature – are reminiscent of jet engines. They conceal
the operation of the air conditioning and the optional deluxe automatic
air conditioning. The high-precision air vents are an example of the
high standards to which the Audi aspires with respect to the function,
design, and workmanship of the entire interior.

High quality: color and trimThe
new Audi TT offers a far more distinct and varied range of colors than
its predecessor. There are 11 exterior colors, one of which is
exclusively for the S line. Seven of the colors in the palette are new
for the TT, and two of these are completely new for Audi: nano gray and
tango red. Panther black, crystal effect and the expressive Sepang blue
are also available for the TTS.

There is also a new palette of
colors for the interior. There are three interior colors to choose from
for both the TT and the TTS. Besides black, these are rock gray and
palomino brown. For the first time, customers can choose a second color –
rotor gray – in combination with the S line package, naturally also
with sporty contrasting stitching. TTS buyers can also choose the sporty
leather shade express red.

The equipment for the new TTS
includes extended interior elements that add individually selectable
color accents to the trims of the S sport seats, the sides of the center
console and the rings of the air vents. Audi offers customers with
exquisite taste numerous options for customization. Upholstery in
various grades of cloth, Alcantara and leather is available for the
seats; there are also three leather packages. The S sport seats have
characteristic diamond patterning on the high quality fine Nappa leather
in the center panel.

The design selection admiral blue is a
particular highlight, making an impression with matching leather colors,
alternately contrasting stitching, dark aluminum, a coordinated paint
finish and a special mesh floor mat.

For the TTS, Audi’s design
engineers have developed an innovative technical laser texture for the
wings of the dashboard. This texture has a honeycomb-like, slightly
raised structure that gives the TTS an unrivaled sporty appeal.

Convenient: the equipmentIn
Germany, sales of the new TT Roadster will begin with the Paris
exhibition in October 2014; the TTS Roadster will follow at the start of
2015. The basic price of the 2.0 TFSI is €37,900. The generous standard
equipment, which includes xenon plus headlights, air conditioning, and
the MMI radio, can be expanded with numerous pieces of sporty,
practical, and convenient optional equipment.

The optional driver
assistance systems are also cutting edge. The Audi side assist included
as standard in the 2.0 TFSI and TTS ensures safe lane changes with a
radar measurement towards the rear, and the Audi active lane assist
keeps the open top two seater in its lane with minor steering
interventions. The park assist with display of surroundings
automatically controls the car into and out of parking spaces. Traffic
sign recognition is another optional system; attention assist is
provided as standard.

Topping the modular infotainment program is
MMI navigation plus with MMI touch. It already uses the second
generation modular infotainment program with the Tegra 30 graphics
processor from Audi’s partner Nvidia. It goes without saying that the
Audi TT features the high speed communication standard LTE (Long Term
Evolution) on board. The supplementary module Audi connect additionally
features the familiar tailored online services – from Google Earth and
Google Street View through to Twitter and Facebook access. Another new
feature is online media streaming. The MMI connect app enables access to
services such as Aupeo! and Napster.

With the Audi phone box, the
cell phone can be conveniently docked in the car and the seat belt
microphone ensures excellent voice quality during calls even when the
convertible top is open. The optional Bang & Olufsen sound system
provides 680 watts of power and features 12 loudspeakers. The specially
designed frames for the woofers are adorned with anodized aluminum
elements bearing the logo of the Danish hi-fi specialists. A white LED
light conductor makes the sound system a highlight even at night.

**The
fuel consumption and the CO2 emissions of a vehicle vary due to the
choice of wheels and tires. They not only depend on the efficient
utilization of the fuel by the vehicle, but are also influenced by
driving behavior and other non-technical factors.
